The Commutative Property of Addition states that for all expressions a and b, ab = ba
The answer to the given statement is FALSE. This is the commutative property of multiplication and not of addition.
What is the commutative property of addition?To "commute" is to move about or travel. According to the commutative property of addition, the sum is unaffected by changes in the order of the numbers being added.
The formula for the commutative property of numbers is A + B = B + A if two numbers A and B are supplied.
A + B = B + A
A × B = B × A
A - B ≠ B - A
A ÷ B ≠ B ÷ A
According to the commutative property formula, the result is unaffected by the sequence in which two numbers are added or multiplied. However, the order of the integers matters for subtracting and dividing any two real numbers, so it cannot be changed.

Write an equation for the line parallel to the given line that contains C.
C(2,7); y=-3x+5
The equation of the parallel line is
(Use integers or fractions for any numbers in the equation. Simplify your answer.)
Answer:
Equation of line is given as y = mx + c, where m is the gradient and c is the y-intercept.
Parallel lines have the same gradient so gradient of line is -3.
Equation of line is y = -3x + c.
Substitute C(2,7) into the equation to find c.
7 = -3(2) + c
c = 13
Hence, equation of line is y = -3x + 13.

The manager of a toy store bought 10 toy cars. The cars came in p packages. Write an expression that shows how many toy cars were in each package.
we can write x = 10/p to represent the number of toy cars x, in each package.
What is an Expression?Expression: An expression is a combination of numbers, variables, functions (such as addition, subtraction, multiplication or division etc.) Expressions can be thought of as similar to phrases. In language, a phrase on its own may include an action, but it doesn't make a complete sentence
The management purchased n cars, which equals 10.
There were p packages altogether, and each box contained one car. Per bundle, there should be x cars
Since there are x cars in each box, p packages would contain x*p cars
The equation can be written as 10 = x*p because we know there were p packages with 10 cars in them.
The multiplication of x and p is indicated by an asterisk (*).
You can write x = 10/p to represent the number of cars x, in each package.
The division symbol is denoted by a slash (/).
Because the number of cars and parcels can only be whole numbers, the values of x and p must also be whole numbers. Since the result of x and p is 10, both x and p must be factors of 10.
The factors of 10 are: 1,2,5 and 10
So, we get the following scenarios:
1 package with 10 cars inside it
2 packages each with 5 cars
5 packages each with 2 cars
10 packages each with 1 car
If the number of cars/packages must be greater than 1, then we have the following two cases:
2 packages each with 5 cars
5 packages each with 2 cars
we can write x = 10/p to represent the number of toy cars x, in each package.

The solution to the inequality expression given as 2 > 8 - 43h is h > 6/43
How to determine the solution to the inequality?The inequality expression is given as
2 > 8 - 43h
Subtract 8 from both sides of the inequality expression
So, we have the following expression
2 - 8 > 8 - 8 - 43h
Evaluate the difference in the above expression
So, we have the following expression
-6 > - 43h
Divide both sides of the inequality by -43
So, we have
-6/-43 > - 43h/-43
Evaluate the quotient
6/43 < h

[tex]x^{2}+5x+3x+15[/tex]
[tex]x^{2} +8x+15[/tex] Answer
Answer: x ^ 2 + 8x + 15
Step-by-step explanation: You can use the FOIL method to multiply. F - first two variables, so the two x.
x • x = x^2
O - outside, the outermost variables in the parenthesis, which would be x and 5.
x • 5 = 5x
I - inside, the innermost variables in the parenthesis, which would be x and 3.
x • 3 = 3x
L - last two variables, so 3 and 5.
3 • 5 = 15
Altogether:
x^2 + 5x + 3x + 15, which simplifies to x^2 + 8x + 15.

2(x-0.1x-2.70)=56.70 step by step pls
For the given equation 2(x-0.1x-2.70)=56.70, the value of x is 7.76
How are equations used?The equals sign is used in mathematical formulas to show that two expressions are equal. The first stage in resolving a variable equation is determining the values of the variables that lead to equality. The variables for which the equation must be solved are known as the unknown variables, while the values of the unknown variables that satisfy the equality are referred to as the equation's solutions. Identity equations and conditional equations are the two types of equations.
Given equation, 2(x-0.1x-2.70) = 56.70
or, 2(0.9x-2.70) = 56.70
or, 1.8x - 5.40 = 56.70
or, 1.8x = 56.70+5.40
or, x = 62.10/1.8 = 7.76

Nathan earns $6.50 an hour, plus tips, as a waiter in a restaurant. Suppose he works 26 hours in a week. How much money in tips must he receive to earn at least $229?
If Nathan earns $6.50 an hour, plus tips, as a waiter in a restaurant, and he worked for 26 hours, then he must receive $60 in tips, to earn a total of $229 in that time period.
As per the question statement, Nathan earns $6.50 an hour, plus tips, as a waiter in a restaurant, and he worked for 26 hours.
We are required to calculate the amount of tips Nathan must receive to earn a total of $229, working for 26 hours.
To solve this question, we will first calculate the amount Nathan can earn from his regular salary rate, working for 26 hours, and then subtract that amount from $229 which he earned as his salary from the restaurant plus his tips while working for those 26 hours.
Therefore, Nathan will earn $(26 * 6.50) = $169 in his regular salary from the restaurant working for 26 hours.
But since Nathan earned a total of $229 working at the restaurant for the same 26 hours, the extra money over his salary must be the amount he earned in tips.
Therefore, Nathan received $(229 - 169) = $60 in tips, to earn a total of $229 working for 26 hours at the restaurant.

The ratio of the deposit Emma paid to the total of the 18 equal payments in its simplest form is 2/3
What is total cost of the van?
The total cost of the van is the its cost plus the VAT of 20%, which is determined as the 20% of the cost, as computed below:
VAT on the cost of van=20%*cost of van
cost of van=£23500
VAT on the cost of van=20%*£23500
VAT on the cost of van=£4,700
total cost=£23500+£4,700
total cost=£28,200

To convert miles per hour to feet per second, which conversion factor would not be used?
To convert miles per hour to feet per second the conversion factor that wouldn't be used is option d: 1 mi/5280 ft and 5 miles per hour will be equal to 7.34 feet per seconds.
As per the question statement, we are asked that which of the given conversion factors, will not be used for converting miles per hour to feet per second.
We should be knowing the following values for conversion:
we know, 1 mile = 1.6 km = 5280 feet
and 1 hour = 60 minutes = 3600 seconds.
Now, mi/hr * 1hr/60min * 1min/60sec * 5280ft/mi
Note that units all cancel out leaving only ft/sec
Hence option d : 1 mi/5280 ft is not appropriate for converting mi/hr to ft/sec.
For e.g., 5 miles per hour = 5*5280/3600
5 mil/hr = 7.34 ft/sec
Hence, to convert miles per hour to feet per second the conversion factor that wouldn't be used is option d: 1 mi/5280 ft and 5 miles per hour will be equal to 7.34 feet per seconds.

Solution:

Subtract the null hypothesis mean from the sample mean. Divide the difference by the sample standard deviation. Multiply the result by the square root of the sample size. The t value measures the magnitude of the difference relative to the variability of the sample data. In other words, T is simply the calculated difference expressed in units of standard error.
The larger the size of T the more evidence against the null hypothesis. The important t-value is the limit of the t-distribution.
